Specification of Letters Patent.

Patented Mar. 14, 1922 Application filed April 29, 1918. Serial No. 231,49 Y p To all whom it mag concern:

Be it known that I, LEONARD B. TERHUNE, of Newark, in the county ofEssex and in the State of New Jersey, have invented a certain new anduseful Improvement in Separating Machines: and do hereby declare thatthe following is a full, clear, and exact description thereof. 7

My invention comprises a machine for applying force to a member or tomembers held together, in such a way as to pull apart said member or.members into sep arate pieces. Y

'The object of my invention is to provide a machine of the abovecharacter which may be used for readily separating the individterlocking with one another. When combs are made in this manner it hasbeen found.

difiicult to separate the two combs from each other as the separationhas been ordinarily effected by hand. Because of the difli? culty ofseparating the combs, howeverya considerable amount of time has beenconsumed in this step of the process, and some of the combs were sotightly fastened to-. gether that they could not be separated-by, hand.It is the. object of my invention to provide a machine which maybe usedto carry out this step of the process which ma-i chine will operatequickly, and easily to separate the combs and without deforming them.However it will. be understood that the machine is notlimited to use forsepar-- ating combs. Further objects of myinvention will appear from thedetailed descrip-- tion thereof contained hereinafter. 1 While myinvention ispapable of einbodi-' ment inmany different forms, for thepur-; pose of illustration, I have shown only one form thereof in theaccompanying drawings,

in which 7 y a Figure 1 is a front elevation .of -a machine made inaccordance with my. invention, certain parts appearing in section;

Figure 2 is a side elevation of the same;

Figure 8 is a plan view of theupper portion of the same; and V Flgure 4s an enlarged diagrammatic plan v ew, showing the combs 1n difi'erentpositlons.

In the drawings I have shown a pair of wooden supporting blocks 1 and 2which support a pair of uprights 3 and 4- attached together at theirupper ends by means of a bed plate 5. The upright 3 is provided near ltslower end with'journaled bearings 6 to receive asha'ft 7 ,on which-ahand lever 8, having a handle 9, .is pivotally carried, said shaft 7furthermore being provided with'a lever arm 10 which is normally movedupwardly by means of aspring 11 attached at one end to said lever 10,and" attheother end to the upright 4. The extrelne end. of the lever 10*normally rests against a stop 12 whichforms a crossbar passing acrossthe "lower portion of the 'upright 4. ;At.its' central portion;the'lever. 10 is connected by a link 18 to abell crank leverl carriedupon a pivot 15in a pair of brackets l6.extending downwardly fromthebedplate 5. Said plate 5 has extending longitudinally throughthe'same, a dovetail groove. 17 to receive three slides 18,19 and 20."The slide-20 has an Opening 21, therein to. receive the upper end ofthe bell crank lever: 13, a slot 22 being provided in the plate 5 topermit the'bell crank lever letwto pass through the same. On said slide20 there is. provided a plate 23 secured thereto by. screws 24=, saidplate hav ing. in the upper surface thereof two cam grooves 25 and 26locatedat an acute angle to eachoothenand which are provided to receiverespectively a pair of rollers 27 and 28; The rollers 27 and 28 arecarried upon the ends. respectively'of levers 31 and 32, which areprovided respectively with; jaws '33 and 34130 engage a pair of combs3'5 and 36, The levers 31 and 32 are "pi'votally con: 1

nected bymeans of arms Y37 and 38 to a single pivot 39carriedupontheaslide 18,

andwhich is held in. its adjusted'position by means ofa set'screw. 4:0in the'plate' 5. Upon thecentral slide 19 there is located anabutmentAlto support therear ends: of the combsl35 and 36,-aset screw 42 beingprovided to hold said slide 19 in its:adjusted position. Y 1

In the operation of my invention, a pair? of twin combs.-are insertedbetween. the

arms 37 and 38 in such a manner that their rear ends rest againstabutment 41 and in such a way that the jaws33 and 34 engage the twocombs outside of the position of the teeth thereon. If necessary, thepositions of the slides 18 and 19 may be adjusted so that the particularpair of combs will be properly positioned in this manner. Thereupon thehand lever 8 is operated, which brings about the rearward movement ofthe slide 20, thus causing the jaws 33 and 34 to firmly grasp therespective combs, and at the same time pull them apart. It will beobserved from an inspection of the assembled parts as shown in thedrawings (particularly Fig. 3), that the short levers 31 and 32 bearingthe jaws 33 and 34 may have'a pivotal movement upon the long arms 37 and38 independent of any movement of these arms; also that the short levers31 and 32 may have a movement together -with the arms 37 and 38, thelatter swinging upon the pivot pin 39. lVhen the unseparat'ed parts ofthe comb are inserted between the long arms 37 and 38, as shown in Fig.4, and the e'am plate 23 ismoved inwardly, the first-mentioned movementis that which necessarily first occurs,-that is, the cam-grooves 25 and26 spread the rollers 27 and 28 apart, thus pivoting the short levers 31and 32 upon the arms 37 and 38, this movement carrying the jaws 33 and34 in an arc inwardly towar(l and at an angle to engage with the endsurface of the comb, thus causing these jaws to firmly grip and, infact, to bite into th'e e nd surface of the comb, as shown in Fig. 4, abiting tooth being provided upon each jaw, as shown in Figs. 3 and 4. Acontinued movement of the cam-plate produces a further separation of therollers 27 and 28, and since during this movement the jaws 33 and 34 arein engagement with the end surface of the cone, the spreading oftherollers 27 and 28 produces a spreading of the aws 33 and 34 bodilywith a 5 "reading movement of the arms 37 and 38 a out the pivot 39, thespreading movement of the jaws separating the two portions of the comb.as shown in Fig. 4. Throughout the entire separating movement, however,it will noted that the aws 33 and 34 will maintain their positionsparallel to the ends of'the twin combs. n this way the twin combs willbe readily separated and with a minimum amount of effort, and by thismeans combs may be separated which could not be separated merely byhand.

While I have describedmy invention above in detail, I, wish it to beunderstood that many changes may bemade therein without departing fromthe spirit of the invention.
